100% agree on those Patagucci bags. I have one of each size and I've taken mine all around the world. They've been on hundreds of plane rides, been tossed on the prickly, rocky desert ground and they're still hanging in there. When they finally give up the ghost, I'll mail them back to Patagonia and they'll give me brand new ones.
I had a Patagonia backpack for YEARS that never had a laptop specific sleeve. When it was finally wearing out I called the Dillon MT outlet to order a new backpack with a sleeve built-in.
P - "It sounds like you're unsatisfied with your current backpack, we'd like to make it right"
Me - "no, it was great, but its finally wearing out and I'd like to have a built-in laptop sleeve"
P - "Sir, if you're unhappy with your previous purchase, we'd love to send you the backpack you're looking at to replace it, if you're willing to send us back the one you have now"
Me - "umm ok, thank you!"
That was ~7 years ago and backpack #2 is going strong.
I love that company's overall customer service but especially their willingness to keep you as a customer.
